Stationary and Time-Resolved Fluorescence Spectroscopy of Humic Acids
Original language description
Humic substances (HSs) play an important role in chemical, physical and geological processes occurring in natural waters and soils. Humic substances are natural organic compounds arising from microbial degradation of decaying plant and animal tissues andsynthetic activity of microorganisms. HSs are among the most widely distributed organic materials on the Earth. They are found not only in soils, peat and brown coals (leonardites, lignites) but also in natural waters, sewage, compost, marine and lake sediments, carbonaceous shales and terrestrial sediments. HSs are known to be polydisperse macromolecules, which are made up to a large extend of aliphatic and aromatic carboxylic acids, phenols and also of higher condensed compounds. The major componentsof HSs are humic acids (HAs), fulvic acids (FAs) and humin (HU) which are defined on the basis of their solubilities in aqueous solution. HAs are soluble in solutions of pH>2, while FAs are soluble at all pH and HU is entirely insoluble.
